STOVE-SHELF.

SPECIFICATION forming part of Letters Patent No. 226,125, dated March30, 1880.

Application filed Au gust 28, 1878.

To all whom it may concern:

Be it known that we, CHARLES H. SPRAY and EDWARD M. BUsH, of Seymour, inthe county of Jackson and State of Indiana, have invented a new andImproved Stove; and we do hereby declare that the following is a full,clear, and exact description of the same.

The object of our invention is to furnish an improvement in the class ofovens of cooking stoves and ranges whose doors have a movable shelf soconnected therewith that the openin g and closingof the doors will slidethe shelf along the bottom of the oven.

Our improvement relates to a shelf or false bottom, which is preferablymade the full size of the true bottom of the oven-chamber, and issupported in guides and moved out and in, as the door opens and closes,by means of a rack and a segmental toothed lever that is suitablyconnected with and operated by the door.

Heretofore the corners of such sliding shelves have been rounded toprevent binding or undue friction with the sides of the oven, and toenable the door to be closed tight at the instant the shelves have beenslid back into the oven.

In the accompanying drawings, forming part of this specification, Figure1 is a side elevation of a cooking-stove provided with our improvement,the oven-door being shown open and sliding shelf or false bottomprojected outward. Fig. 2 is a horizontal section on line a: w of Fig.1, showing the parts in the same position.

Aindicates a cookin g-stove provided with our improved oven attachment.The shelf or false bottom B is rectangular and of the same size as thetrue bottom 0 of the oven. It is placed near the bottom 0 and slideshorizontally in guides or ways D, formed by parallel ribs cast on theside plates of the oven.

The shelf is provided on the under side with a rack, E, which is cast inone piece with it, and extends across its middle in the direction of itswidth-z. 0., between the two oven-doors.

The shelf is caused to slide in its ways D, so as to move in or out, bymeans of a segmental gear, E, which is pivoted to the oven-bottom 0, andconnected with the door G by means of a curved rod, H. The latter ispivoted, in such a manner as to allow its convenient detachment in caseit should, for any reason, be desirable to have the false bottomstationary.

It is obvious that when the oven-door G is opened the tension of the rodH on the segmental gear F will rotate the latter on its pivot and causeit to act as a lever on the rack E, with which its teeth engage, so asto push or slide the shelf B forward, and thus cause it to project fromthe oven more or less, according as the door is opened more or lesswidely; and, contrariwise, when the door is closed the rod H will pushand thereby turn the segmental gear F back to its original position, andthus cause it to draw the shelf B inward again, or back to its originalposition. Thus, by the simple operation of opening the door, the shelfor false bottom is brought forward into convenient position to receivepans or other receptacles of food to be baked, and by closing it saidpans or receptacles are carried into the oven. Similarly, if it isdesired to ascertain the extent to which the baking has progressed, theopening of the door will bring the pans forward, so that the desiredinspection can be easily made.

The false bottom B is perforated throughout its whole extent, andlocated above the true bottom G a sufficient distance to leave a narrowspace beneath it.

This construction and arrangement of the false bottom will obviouslyprevent the dough or other material being baked from being subjected tounequal heat at the bottom of the pans or other receptacles, since thelatter do not rest directly on the true bottom 0, which is the hottestpart of the oven-sides.

What we claim as our improvement is- In combination with the stove-ovenand the horizontally-swinging oven-door G, the sliding false oven-bottomB, provided on its under side with the rack E, having lateral teeth, andthe toothed lever F, pivoted flat on the true bottom 0, and the curvedconnecting-rod H, pivoted to door and lever, all arranged as shown anddescribed, to operate as specified.
